FREDERICK GRANDISON SARGENT, OF GRANITEVILLE, MASSACHUSETTS.

MACHINE FOR DUSTING FIBER.

SPECIFICATION forming part of Letters Patent No. 394,017, dated December4, 1888. Application filed July 10, 1888. Serial No. 279,557. (Nomodel.)

To all whom it may concern:

Be it known that I, FREDERICK GRANDISON SARGENT, of Graniteville, in thecounty of Middlesex and State of .llassachusetts, have invented acertain new and useful Improvement in Machines for Dust ing Fiber, ofwhich the following is a specification. My invention relates tocone-dusters; and 1t consists in certain new improved constructions andcombinations of the several parts thereof, substantially as hereinafterdescribed and claimed.

In the drawings, Figure 'l is a side elevation of a coneduster providedwith my improvements. Fig. 3 is an end elevation of the same. Fig. 4 isa vertical longitudinal section through the same. Fig. 5 is an endelevation of a portion of the same, with the end casing of the cylinderand feed-apron removed to show the relation of certain of the workingparts.

1 is the frz'tn'ie-work of the machine.

:2 is the conical casing of the cone-duster.

3 is the openin through which the fiber is delivered from thecone-duster after being operated upon.

4 is the cone-duster cylinder, composed of bars sustained upon arms, soas to have its exterior path in the form of the frustum of a cone,corresponding to the shape of the casin g. This cylinder is mounted uponthe shaft- 5, which is sustained in boxes upon the frame, and has thetight and loose pulleys (i 7 attached thereto, by which it is drivenfrom any suitable counter-shaft. The outer faces of the bars forming thecone-duster cylinder are provided with teeth or spikes, as shown inFigs. 4 and 5, for the purpose of working the fiber and opening it upand removing the dust and dirt therefrom.

The fiber is fed into the machine by means of the feed-apron S, which ismounted upon rollers 9 9 at each end, in the usual manner. Upon theshaft of one of the rollers 9 is attached the pulley 1.0, by which thefeed-apron is driven. the apron at the point where it feeds the fiberinto the casing of the cone-duster cylinder. This roller serves tocompress the fiber at that point and present it more certainly to theaction of the cone-duster cylinder. This squeeze- Fig. is a top planview of the same.

A squeeze-roll, 11, is placed over i roll is adjusted and held inposition at a ceri' tain height above the feed-apron by the setscrews 1212, which bear upon the upper side of its boxes and prevent its risingmore than a certain distance. 7 feed-apron and roller 11 and itsset-screws ii is of the ordinary character and well understood, as isthat of the other parts of the machine heretofore described.

The lower portion of the casing of the coneduster cylinder is formed of.slats ,1 3, opening into an inclosed space, 14, underneath the machine,and through these slats the heavier dirt and impuritiesremoved from thefiber by the cone-duster cylinder drop downward and are thuspern'lanently removed from the fiber; but there is a certain amount offine dust which is too light to drop downward of its own weight andcontinues to float within the casing of the cone-duster, and isdelivered through the opening 33 with the fiber remaining in it to alarge extent. To remove this light floating dust, I surround thecone-cylinder with the wire-screen netting l 5, as shown in Fi 1t and 5,and in the end of the casing, opening within the inclosingscreen-covering and at the end of the cone-duster cylinder, I providethe opening or passage 11;. Outside of the opening 16 and inclosing thesame I provide the box 17, which extends downward past the end of thecasing of the cone-duster cylinder and over the top of the same for somedistance toward l its larger end. in top of this box I mount the fan 18,and provide passages l I 19, formed by easing the ends of the fan andopening this casing into the box 17, as shown. The fan takes the airinfrom. these passages atits 3 center and delivers it outward through thespout 20, attached thereto. The fan 18 is of ordin ary construction ,monnted upon the shaft 2] which is supported in boxes in the casing of thefan in the ordinary manner, and is pro vided with a tight and loosepulley, 22 23, on one end of it for driving it from a suitablecounter-shaft. Outside of these another pulley, 24, attached to theshaft, to which the pulley 10 of the feed-apron is belted, thusproviding for the driving of the latter. The

squeeze-roller 11 is rotated by the friction of the fiber which iscarried underneath it by the feed-apron.

The construction of the' In order to regulate the draft of the fan fromthe center of the cone-cylinder, I provide an opening, 25, through theend of the box 17,

which is covered by a slide or valve, 26, working up and down in groovedstrips 27, attached to the face of the box 17 which are rabbeted ontheir inner edges to allow the valve 26 to slide behind them. The valveis provided with a knob to raise and lower it. By opening the valve 26,the draft of air to the fan will be partially supplied through theopening 25 and partiall x through the opening suitable passages with thebox 17 and adapted to exhaust the. air through the same from the centerof the screen-covering of the cylinder and to deliver it outside of thecasing of the machine, substantially as described.

2. The combination of the cone-duster cylinder provided with teeth orspines on'its exterior and surrounded by the screen-covering 15, the boxor inclosure 17, opening into the center of the cone-duster cylinderwithin its screen-covering, the fan 18, connected by suitable passageswith the box 17 and adapted to exhaust the air through the same from thecenter of the screen-covering of the cylinder and to deliver it outsideof the casing of the machine, and the opening 25 into the box 17,provided with the valve 26, arranged to cover the said opening or exposemore or less of it, substantially as described.
